I've been doing ad design for newspapers in InDesign and Quark 4.0 on both Mac and PC for about 4 years or so.
Every JPG photo that comes my way I automatically convert it to TIF format to use it in whatever ad or layout I'm working on.

Recently someone with a fair amount of design experience asked me why I bothered converting the JPGs to TIFs, and said that JPGs work just as well.

I was about to defend my actions when I realized that I have no idea why they have to be converted - it was something I was taught in college to ALWAYS do, but no real explanation was ever given.

What's the consenus out there? In preparing documents for print on web press and occasionally full colour glossy presentations, is there any significant difference between using JPGs or TIFs?

It's really just an academic question for me, but I am genuinely curious.
